The Rip-Cut is a no-nonsense, straight forward, accessory for your circular saw. It features a durable design including a solid aluminum guide rail, an easy-to-read adjustable scale, and a reversible guide arm which works whether you're left or right handed and whether your blade is on the left or right side of the saw. It's an incredibly easy, precise, and affordable way to break down large panels for almost any project.
